| titleOfInvention | Recovery of ethylene, chlorine and hc1 from vented waste gas from direct chlorination reactor |
| abstract | ABSTRACT OF THE DISCLOSURE A process is provided which reduces the corrosion in an ethylene dichloride (EDC) producing process which uses a high temperature direct chlorination (HTDC) reactor and an oxychlorination reactor; the process comprises: (a) reacting wet chlorine, having a moisture content in the range from 100 ppm to about 1% by weight of the chlorine feed, with an excess over stoichiometric of ethylene in a liquid chlorohydrocarbon medium at a temperature of at least about 50°C at atmospheric pressure or above, to yield product EDC in a draw-off from the HTDC reactor, (b) separating product EDC from higher boiling components in said draw-off from the HTDC, in a vapor-liquid separating means, (c) condensing overhead from said separating means in an overhead drum so as to condense the major portion of the EDC, and vent a stream consisting essentially of nitrogen, ethylene, chlorine, HC1 and less than 1.5% by wt. of water, based on the weight of the vent stream, (d) cooling the vent stream to a temperature in the range from about -30°C to 0°C to condense condensables in the vent stream and freeze water, (e) separating said water and condensables from non-condensables including nitrogen, chlorine, ethylene and HC1, without plugging lines with ice, and (f) recycling said non-condensables essentially free of water to said oxychlorination reactor, whereby corrosion due to the presence of water in the recycle line and equipment is minimized. |
